Lol, I remember trying to do this one for the achivment. Finally after a certin point 4 entier full partys wound up joining in along with half a dozen solo players in order to beat that thing. And we finally mannaged to do it. But there were still a field of corpses after we won by the skin on our backs too.

That FATE boss is insainly hard. Even Odin and Behemoth don't take that much server colaberation to beat.
